Corrections and suggestions:
-MP40 has 32 bullets, try researching
-I said this once and I'll say it again, M1A1 physically can not fit drum mags, so give it a 30 shot stick mag.
Suggestions:
You absolutely need:
-Mosin-Nagant: 5 shot bolt action scoped (scoped reloads 1 shot at time) and unscoped (clip at a time, follow this rule with all scoped/unscoped rifles)
-M1 Garand, 8 shot and clip ejects from top with "DING!" when out
-B.A.R.: 20 shot LMG
-Kar98k: ? shot bolt action rifle, scoped and unscoped
-Lee Enfield: 10 shot bolt action rifle
Would be cool:
-M1 Carbine: 15 shot carbine
-Panzerfaust: 1 shot rocket, should go away after use
-Some kind of shotgun for America at least
-Tokarev pistol, like the M1911 but Russian
-Bren LMG
-MMGs for each country (can't find British or Japanese), should be set up by right clicking like Strato's .30 cal
America: M1919A6
Russia: Degtyarev-Pekhotny 28, drum mag flat on top, you'll see
Germany: MG-34
And for the love of god no raycasting.
